GEORGE .I. RAITHEL, OF IIIIDDLEVILLE, NEYV YORK.

HUB.

SPECIFICATION forming part of Letters Patent N0. 398,652, dated February 26, 1889.

Application filed October 1, 1888.

To aZZ whom it may concern: l

Be it known that I, GEORGE J. RAITHEL, of Middleville, in the county of Herkimer, in the State of New York, have invented. new and useful Improvements in Vehicle-Vheels, of t which the following, taken in connection with the" flCCODlPf IHYIDQ drawings, is a full, clear, 1 and exact description.

This invei'it-ion relates to the illlt'ltflllllt'illh oi? spokes in a wheelhub and to seeu ring them I therein and re-enforcing them against both lateral and longitudinal strain.

The object of n'lyinvent-ion is tostrengthen and stiffen the wheel by forming a metallic grip around the hub and around the shoulders of the spokes, gripping positivelyboth 1 the hub on either side of the spokes, and also the shoulders of the spokes, thereby preventing, first, the splitting of the hub, and, secon dl y, preven ti n g the withdrawal of the spokes from their mortises, such grip consisting of a continuous integral band of metal east onto the hub and over the shoulders of the spokes alter the spokes are driven; and my inven tion consists in this re-euforcement and gripping ot' the hub and of the shoulders of the spokes.

In the annexed drawings, Figure l. is aside view of a wheel-hub with portions of some of the spokes atlaclu-nl thereto. Fig. 2 is a trans- 1 verse section on line $.13, Fig. 1. Fig. 3 is a longitudinal section on line 1 y, Fig. 2; and Fig. -l is a transverse section on line 2, Fig. 1, showing the method and means of applying the metal band to the hub.

Similar letters of reference indicate corresponding parts.

A represents the hub, which may be of metal or wood, and (z (1 denote the spokes, which I secure to the hub in the following 1 man ner: I form the exterior of the hub with an annular peripheral groove, [1, around the row of mortises r." r, and of a width somewhat greater than the width of the said mortises. I drive the spokes into the mortises e 0 until the shoulders (Z (Z of the spokes are ln'ought to bear on the h nb, as illustrated in Fig. 2 of the drawings. I then place around l l l l l l l the hub a mold, e, which incloscs the groove 1') and bases of the spokes, and is made in two parts with ports at the junction of said parts to allow the spokes to protrude from the mold 1 Serial No. 236,854:- (No model.)

when applied, illustrated in Fig. :1: of the drawings. The interior of this mold IS 01": the diameter and shape required of the exterior of the hub on the line of the attachment of the spokes. After the mold has thus been applied I pour into the same suitable molten metal, preferably Babbitt metal, and fill the mold therewith, and when cooled and hardened I remove the mold.

In this manner a solid band, ll, of metal is formed in the annular groove, which grips closely the hub adjacent to the spokes on both sides, and also 1 grips the shoulders of the spokes and part of each spoke adjacent and exterior to the shoulders thereon, and such gripping both on the edges of the spokes and upon the shoulders and adjacent to the shoulders effectually prevents the spokes from working loose.

It will be observed that my invention consists in the positive grip oi? the metal band upon the spokes exerting itself d irectlyagai 11st the sides and shoulders, thus bracing and 1 staying the spokes, as well as the hub, and

tl'iereby reducing the liability or possibility 1 of the dishing of wheel to the minimum, if

not absolutely preventing it.

Having described my invention, what I claim ashew, and desire to secure by Letters Patent, is-- l. The re-eut'orcement ol' the spokes of a wheel, consisting in forming an annular peripheral groove in the hub of greater width than the spoke-mortises, then driving the spokes into the hub, and then casting metal into the groove and over the shoulders of the spokes.

2. The gripping of the shoulders of the spokes of a wheel and the spokes themselves adjacent but exterior to the shoulders by casting a metallic band into an annular pe ripheral groove in the hub and around the spokes and their shoulders after the spokes have been driven into the hub.

In testmony whereof I have hereunto signed my name, in the presence of two witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 21st day of September, isss.
